SPLICE.

Application led September 18, 1928. Serial No. 306,779.

This invention relates to splices and more articularly to a splice between fleXlble caiile and rope and a means for protecting the same.

An important obj ect of the invention 1s to provide a device of this character which will protect the rope at the splice against the fraying ordinarily occurring due to Contact of the rope with the wall of a bore through which it is passing, and more particularly to an improvement in protectors for such splices of the type indicated in my prior Patent, No. 1,651,339, granted November 29, 1927, for splices.

As pointed out in this patent, in oil well drilling apparatus, splices of this character are very often employed and since the bore of an oil well is usually crooked, there is a natural tendency of the splice to come in Contact with the well casing. This tendency, increased by the whipping7 of the rope and cable in operation causes a considerable friction which is most noticeable at the increased diameter afforded by the splice.

Since the splice isv naturally weak and the cable is relatively stiff with relation to the rope, there is an increased tendency to breakage at this point, for there are more acute bends in the rope and, as pointed out, a greater friction thereon. Accordingly, an important object of this invention is to provide a splice protector for use in connection with such splices in which the number of parts is reduced to a minimum, the difliculties of application of the protector are practically eliminated and, at the same time, a structure provided over which a rope knife may be passed.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation of a partially completed splice having a cover constructed in accordance with my invention;

Figure 2 is a vertical sectional view through the completed splice;

Figure 3 is a fragmentary side elevation illustrating the manner of reducing the cable;

Figure 4 is a section on the line 1--4 of Figure 2.

In the drawings, I have illustrated a splice between cable and rope constructed in the usual manner of forming the same. This splice is usually formed b separating the strands S of the rope an laying the cable C therein as a core. In order that the rope strands, when rewound about this core, may not be formed with too abrupt a shoulder at a point intermediate the ends of the splice, a number of the strands S of the cable are cut-away, leaving only two or three strands thereof, which extend to the lower end of the splice. It will be obvious that when the rope strands are Wound about a cable reduced in this manner, the diameter of the rope in the complete splice will increase at two points 10 and 1l. The free ends of the strands of the rope are usually thinned before wrapping the same about the cable, with the result that the upper end of the splice tapers fairly sharply, as clearly indicated at 12.

In accordance with the present invention, I provide a tubular sleeve, generally designated at 13, which is" of a lengthslightly greater than the length of the splice, disregarding the tapered portion 12. This sleeve has its lower or rope engaging end tapering from a point approximating the reduction of the cable at 1l to its lower end, as indicated at 14, and the upper end thereof is of uniform diameter. This splice cover is formed of a rubber tube having a fabric core or lining 15. At its upper end, this fabric lining is provided with a continuation in the form of two or more diametrically opposed strips.

lVhen the cover is ap lied, the upper end of the tube aligns wit the lower end of the tapered portion 12 and the strips 16 are wound about the tapered portion 1n opposite directions to form a binding thereon and an anchor preventing the tube from moving downwardl This binding forms a, tapered upper end for the tube, more clearly shown at 17,'and over this tapered upper end of the tube, a metal cap 18 is applied, which is secured by means of securing elements 19 which are of such length that the will not extend into or damage the cable A splice protector of this character may be very readily and rapidly applied to the cable and being formed of sand blast or some similar grade of rubber, will have a wearing quality as great as that of the rope, so that its replacement will only be necessary when the rope is replaced.

It will be obvious that the construction employed is capable of a certain range of change and modification without materially departing from the spirit o 'lf the invention and I accordingly do not limit myself to such specific structure except as hereinafter claimed. v

I claim v l. The combination with a rope t'o cable splice in which the cable is laid as a core to the rope and is reduced in size intermediate the ends 'of "the splice 'and the ends oi:l the rope strands are reduced in orden" that the splice taper at its upper 'end from its larg-'est- 'diameter to the diameter of the cable, of a flexible sleeve sirrounding and fitting the splifceffro'm the lower end of the taper to a pointslightly below the lower end of vthe cable and fitting about the rope, said tube having 'at its upper 'end flexible extensi'oiisadapted to be wound upon and lto cover said tapered portion, and a tapered cap f1ttin'g vover the tapered portion and the 'cover y provided b'y sai'd lieiiible extensions.
